Hi, I cannot find the vTPM config option CONFIG_XEN_TPMDEV_BACKEND in the config file of pv-ops kernel, such as kernel 2.6.32.50. However, this option exists in the config file of kernel version 2.6.18.8. I also cannot find the vTPM backed driver (such as linux-2.6.18-xen.hg/drivers/xen/tpmback ) in the pv-ops kernel. So, how can I configure and use the vTPM backend driver in kernel 2.6.32? Thank you for any advice. Best Regards, Gavin _______________________________________________ Xen-users mailing list Xen-users@lists.xen.org http://lists.xen.org/xen-users

Re: [Xen-devel] How to use the vTPM backend driver in the pv-ops kernel
The frontend driver is currently being ported to the latest kernel. You can find the patch cross listed here as well as the linux kernel mailing list. I have no plans to port the backend driver. If you need it you''ll have to get it from the 2.6.18 kernel and port it yourself. ________________________________________ From: xen-devel-bounces@lists.xen.org [xen-devel-bounces@lists.xen.org] On Behalf Of gavin [gbtux@126.com] Sent: Sunday, December 23, 2012 8:04 AM To: Pasi Kärkkäinen Cc: xen-users@lists.xen.org; xen-devel@lists.xen.org Subject: Re: [Xen-devel] How to use the vTPM backend driver in the pv-ops kernel Hi Pasi, Thank you very much for your information.
